DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 and FIG. 2 show a first embodiment of a bunch winding processing apparatus according to the present invention. The bunch winding apparatus includes a feed pawl member 21 abuts the peripheral side surface of the paper tube 9 end bunch winding has been applied, Ri formed by the rotating means 22 for rotating the package P around the axis, feed
Peripheral side surface of end of paper tube 9 by claw member 21 and rotating means 22
Pulling mechanism 2 for pulling the bunch winding thread wound on the main winding side
3 and the end of the paper tube 9 near the position where the feed claw member 21 contacts.
A seal sticking mechanism (fixed
(Fixing mechanism) 61.

The bunch winding thread 3 has a bunch winding 3b in which the yarn end at the beginning of the winding is hung on a slit formed in the paper tube 9 and is wound in a superposed manner. ) 5 and the bunch feed 3a, and since this kind of package P is continuously wound by a take-up winder, the number of turns of the bunch feed 3a and the bunch feed 3b to the bunch feed 3b. Position 2 where 3a comes out
The position 6 at which the bunch feeder 4 and the bunch feeder 3a enter (traverse) the main winding 5 differs depending on the individual package P.
The package P to be processed is held by a paper tube chuck 26 provided on a base plate 25 that moves in the axial direction. The shaft 27 of the paper tube chuck 26 extends along the axis 28 of the paper tube 9 and
5 is fixed via a bearing block 29 provided in the apparatus.

The feed claw member 21 is formed of a belt-like plate which extends substantially in parallel with the axis 28 and is appropriately bent. The tip 30 is bent in a U-shape to form the top of the peripheral side surface (near the axis position when viewed from above). ). A vertical cylinder 31 extending in a direction intersecting with the shaft 27 is fixed to the bearing block 29, and a base end of the feed claw member 21 is attached to a distal end of the advance / retreat rod 32. That is, the feed claw member 21 is lowered by the contraction, and the leading end 3
0 is abutted.

The rotating means 22 includes a sprocket 3 attached to an extended end of a shaft 27 passing through the base plate 25.
3 and a rotation motor 3 attached to the base plate 25
4 and a sprocket 3 attached to its output shaft 35
6, and a chain 37 stretched between the sprockets 33 and 36, and is rotated in the same direction A as the winding rotation direction of the package P.

The other end of the paper tube 9 of the package P is held by a rotatable peg (not shown).

Next, the operation of the first embodiment will be described.

The approach of the base plate 25 causes the distal end of the paper tube chuck 26 to fit into the end of the paper tube 9 to hold and fix the package P. Then, due to the contraction of the vertical cylinder 31, the feed claw member 21 descends, and its tip 30 comes into contact with the peripheral side surface of the end of the paper tube 9. Next, the rotation motor 34
Operates to rotate the package P at least once through the shaft 27 and the paper tube chuck 26 (rotation direction A). By this rotation, the bunch yarn feeder 3a always engages with the leading end 30 of the feed claw member 21 and is brought closer, and as shown by the two-dot chain line in FIG. It is in a state of heading.

Therefore, it is sufficient that the fixing sticker of the bunch feed thread 3a is attached to the vicinity of the upstream side in the rotation direction A of the tip 30 of the feed claw member 21 (the hatched portion 38 in FIG. 2), and the bunch feed is reliably performed. The thread 3a can be fixed. Further, the cutting position of the bunch feed yarn 3a is changed to the seal attaching position 38.
2 (shown by a broken line 39 in FIG. 2), and stable bunch processing is achieved.

The rotating means may be any as long as it can relatively move the feed claw member 21 and the peripheral side surface of the paper tube 9 in the circumferential direction. The package P is fixed and the feed claw member 21 is moved along the peripheral side surface. It may be configured to turn.

Next, a second embodiment of the present invention will be described with reference to FIGS.

The feed claw member 42 of the thread pulling mechanism 41
The tip 43 is bent obliquely downward so as to come into contact with the top of the paper tube 9.
It is attached to a moving block 45 provided on a shaft 44. The shaft 44 is provided with a screw 46, and the moving block 45 is screwed to the screw 46.
The moving block 45 is provided with a detent rod 49 that extends parallel to the shaft 44 and fits into the shaft hole 48 of the bearing block 47. Therefore, the feed claw member 42
When the package P rotates forward and backward by driving the rotation motor 34, the package P moves back and forth in the direction of the axis 28 in synchronization with the forward and reverse rotation. The pitch of the screw 46 is set to about 1/2 of the average value of the winding pitch p of the bunch yarn feeding 3a. That is, the bunch feed 3 in the package P
Regardless of the winding shape of a, when the package P is rotated twice in the anti-winding direction B, as shown by the two-dot chain line in FIG. In contact with and according to the slide of the feed claw member 42,
The yarns are arranged spirally at equal intervals without overlapping. Accordingly, the yarn path extends from the leading end 43 of the feed claw member 42, and the sticking position 38 and the cutting position 39 of the seal are the feed claw members 42 after sliding.
Can be set in the vicinity of the tip. Since the other configuration and operation and effect are the same as those of the first embodiment, the same reference numerals are given in the drawings and the description is omitted.

By utilizing the yarn shifting mechanism 41, the number of windings of the bunch yarn feeding 3a can be determined. That is, in a later process, when a continuous yarn is connected to the surface yarn (end of winding end) of the adjacent package P in a state of being inserted into a creel or the like and used as a continuous yarn, the minimum required length of the end yarn at the start of winding is considered. Is determined. Therefore, the package P to be processed
However, it is desirable to determine at this stage whether or not it has this length.

FIGS. 5 and 6 show a yarn pulling mechanism 51 having the function of determining the number of windings.
A bracket 53 attached to one of the reciprocating rods 32 is swingably supported via a longitudinal axis 54, and a sensor 55 for sensing the swing is provided on the base end side. A coil spring 56, one end of which is fixed to the bracket 53 and the other end of which is engaged with the feed claw member 52, is provided on the longitudinal axis 54 so that the feed claw member 52 is turned on the opposite side to the rotation direction B (counterclockwise in the figure). Is energizing. The bracket 53 is provided with a stopper 57 that abuts on a side portion of the bracket 53 in order to hold the urged feed claw member 52 substantially in the direction of the axis 28. Sensor 5
Reference numeral 5 denotes a U-shape that vertically sandwiches the base end of the feed claw member 52, and is normally mounted at a position appropriately separated clockwise from the base end. That is, the bunch feed 3
If a is less than the maximum number of two turns, the leading end 43 of the feed claw member 52 advances during the slide due to the yarn tension at or before the point 24 where the bunch feed yarn 3a comes out of the bunch rod winding 3b. Blocked, feed claw member 52
Swings clockwise. The sensor 55 detects the swing of a certain amount or more, issues an alarm, and interrupts the subsequent processing. That is, the bunch feed 3
It is possible to select the package P having the insufficient number of turns of a, thereby contributing to quality improvement of the package P. The other configuration is the same as that of the second embodiment, and a description thereof will be omitted.

Next, a specific embodiment of the present invention will be described with reference to FIGS.

In this specific embodiment, the bunch winding processing apparatus shown in the second embodiment is a
And a seal sticking mechanism 61 for sticking a seal to fix the aligned bunch feeding yarns 3a to the paper tube 9 in addition to the above-described yarn pulling mechanism 41. A yarn cutting mechanism 62 for cutting the yarn feed 3a and a yarn removing mechanism 63 for sucking and gripping the cut yarn are provided.

As shown in FIG. 8, the package P is transported by a transport conveyor 64 in a peg table
The paper tube 9 is held so that its axis 28 is slightly inclined from horizontal and the end on the bunch winding side of the paper tube 9 faces upward. Above the stop position of the package P, a support frame 67, one end of which is fixed to the base 66, extends in the transverse direction of conveyance and the axis 2 of the package P.
It extends parallel to 8. The support frame 67 is provided with a seal sticking mechanism 61 disposed almost directly above the package P, and the base plate 25 is provided movably in the direction of the axis 28 of the package P. The seal sticking mechanism 61 is a well-known type in which stickers having an adhesive surface are pressed one by one to target positions by descending the arm 68 and are stuck to a predetermined position (38) at the end of the paper tube 9. Is set. In addition, the base plate 25 includes
A paper tube chuck 26 held on the axis 28 of the paper tube 9 is provided, and a yarn cutting mechanism 62 and a yarn removing mechanism 6 are provided near the paper tube chuck 26.
3 are arranged.

The yarn cutting mechanism 62 is disposed near the downstream side in the rotation direction B of the feed claw member 42 and has a heat cutter 70 having a tip 69 to be heated and a heat cutter 70 for moving the heat cutter 70 toward the paper tube 9. Cutter moving cylinder 7
1 and 1. Cylinder 71 for moving cutter
Is attached to the base plate 25 via a bracket 72, and the heat cutter 70 is attached to the axis 28 by a holding bracket 73 attached to a reciprocating rod (not shown).
It is held obliquely with respect to. The extension causes the distal end portion 96 of the heat cutter 70 to approach or contact the cutting position (39). Instead of the heat cutter 70, a cutter having a thread cutting blade may be provided.

As shown in FIG. 4, the cutting position needs to be in the vicinity of the seal sticking position 38 and in a range 74 where there is no slit on the circumference of the paper tube 9. For this reason, for example, the position of the cutting target point (processing start origin) in the package P is previously determined by a paper tube position determining device (see Japanese Utility Model Laid-Open No. 5-3270) previously proposed by the present applicant. And This paper tube position indexing device is provided with a non-slit area 7 on the peripheral side of the paper core 9.
A groove (or a color mark) in the axial direction is formed in a part of 4 and the position is detected by a convex rotational position sensor (or a color sensor) that engages with the groove.

Next, the yarn removing mechanism 63 includes the heat cutter 7
It is arranged in the vicinity of the feed claw member 42 on the opposite side to 0, and is configured as an air sucker that sucks a thread by air force. The suction mouth 76 of the suction mouth 75 is connected to the paper tube 9
Is held so as to approach the peripheral side surface of the paper tube 9 and cut along the entire circumference of the paper tube 9 by repeating suction and rotation movement in cooperation with the rotation of the package P by the paper tube chuck 26. The yarn is sucked and removed. Further, in this embodiment, a yarn bundle holding member 77 is provided to prevent the yarn at a position distant from the suction port 76 from being caught when the yarn is sucked.

As shown in FIG.
Has a passage 78 for suction air C therein, and is located near a proximal end opening 81 to which a twisting nozzle portion 79 located near the suction port 76 and a discharge pipe 80 are connected. A suction nozzle portion 82 and a yarn chucker 83 located between the nozzle portions 79 and 82 are provided. The suction nozzle section 82 has an annular air pressure chamber 83 formed coaxially with the suction air passage 78 and an air ejection path 85 partitioned so as to be inclined to the base end side by a cone body 84 formed inside thereof. The supply of the compressed air causes the air to be ejected to the base end side, thereby substantially forming the suction air C. As shown in FIG. 10, the twisting nozzle portion 79 includes a concave chamber 86 formed coaxially with the suction air passage 78 and supplied with compressed air, and a nozzle pipe 87 that defines the suction port 76. , This nozzle pipe 87
In addition, a nozzle hole 88 is formed which extends from the concave chamber 86 to the suction air passage 78 in the circumferential tangential direction and in the suction direction. That is, a swirling flow is generated in the suction air passage 78, and several yarns to be sucked are collectively twisted.
The number of the nozzle holes 88 is not limited to the four illustrated ones, but may be any number as long as a swirling flow can be formed. Yarn chucker 83
Is composed of a cylinder 89 provided in a direction transverse to the suction air passage 78 and a chuck body 91 attached to the tip of the reciprocating rod 90. The chuck body 91 is opposed to the chuck body 91 with the suction air passage 78 interposed therebetween. By appropriately contacting the block 92, the sucked yarn bundle is gripped or released at a predetermined timing. That is, the cut bunch winding thread 3 is detached from the paper tube over the entire circumference by repeating air suction, chuck holding, package rotation, and chuck holding release.

As shown in FIGS. 7 and 11, the thread bundle holding member 77 is provided on the upstream side in the rotation direction B of the suction mouth 76, and has a sliding contact portion 93 at one end which is in contact with the peripheral side surface of the paper tube 9. It is formed as a substantially U-shaped lever plate. The sliding portion 93 is bent along the peripheral side surface of the paper tube 9,
A pad 94 large enough to cover at least the bunch rod winding 3b is attached to the bent surface. Thread bundle holding member 7
7 has a vertical pin 95 attached to the other end thereof and a bracket 9.
6, and is rotatably supported by a bearing block 47. At the other end corner, a reciprocating rod 98 of a swing cylinder 97 attached to the base plate 25 is pivotally supported via a bracket 99.
7 is swung in the horizontal direction. That is, when the yarn is sucked by the suction mouth 75, the yarn bundle pressing member 77 is swung clockwise in FIG. 11 to press the sliding contact portion 93 against the peripheral side surface of the paper tube 9 of the rotating package P. I have. The material of the pad 94 is not limited to an elastic body but may be a metal as long as it has an appropriate frictional force that does not allow the thread bundle to be sucked out.

In addition, the bunch winding processing apparatus is provided with a control panel (not shown) for automatically operating the cylinders 31, 71, 89, 97 and the rotation motor 34 at a predetermined timing. The interlocking control is performed according to the operation of a sensor (not shown) for detecting the position of the chain 37 and the moving block 45 and the like.

Next, the operation of this embodiment will be described (see FIG. 12).

When the package P conveyed by the conveyer is stopped at the position of the station S, the paper tube chuck 26 moves the paper tube chuck 9 by the approaching movement of the base plate 25.
And the paper tube 9 is gripped (ST1). Next, the feed claw member 42 is operated by the operation of the vertical cylinder 31.
Is lowered, and its tip 43 comes into contact with the peripheral side surface of the paper tube 9 (ST2). Then, the driving of the rotation motor 34 rotates the paper tube chuck 26, whereby the package P makes two rotations in the predetermined direction B (ST3). By this rotation, the feed claw member 42 slides in a direction away from the main winding 5 of the package P, and transfers the bunch feed yarn 3a to the front end 43 of the feed claw member 42.
To be engaged. At the end of this rotation, the yarn path of the bunch yarn feeding 3a is spirally aligned at substantially equal intervals from the position of the leading end 43 of the feeding claw member 42 to the main winding 5. In the case where the yarn pulling mechanism 51 shown in FIGS. 5 and 6 is employed, when the feed claw member 52 swings by a predetermined amount due to the tension of the bunch yarn feed 3a (ST3a), the sensor 55 Is detected, and it is determined that the number of windings of the bunch yarn feeder 3a is two or less at the maximum (ST3b), and an alarm is issued (ST3b).

When the alignment of the bunch yarns 3a is completed, the arm 68 of the seal sticking mechanism 61 is lowered to a position near the tip 43 of the feed claw member 42, that is, a predetermined length from the main winding of the aligned bunch yarns 3a. A sticker is attached to the position separated by just a distance and fixed to the paper tube 9 (ST4). Next, the package P is rotated appropriately, and the seal portion is
After being moved to the position facing 0, the leading end 69 of the heated heat cutter 70 is brought closer or in contact with the cutter moving cylinder 71, so that the bunch thread 3
Cut the vicinity of the seal rod winding side a and the bunch rod winding 3b (ST5). When this cutting is completed, the cutter moving cylinder 71 contracts and the heat cutter 70 returns to the original position.

When the bunch yarn feeding 3a and the bunch rod winding 3b are cut, the yarn bundle pressing member 77 is swung by the operation of the swing cylinder 97, and the sliding contact portion 93 of the paper bunch is properly separated from the cutting position 39. Hold down the tube position. Then, the suction yarn 75 sucks the free yarn. At this time, the swirling flow formed by the twisting nozzle portion 79 bundles the cut bunch yarn 3a and the bunch rod-wound 3b wound on the slit, and enters the slit due to the force of the swirling flow. The thread of the bunch 3b is pulled out. Thread bundle holding member 7
When a portion of the yarn that is not pressed by the suction nozzle 7 is sucked by the suction air, the yarn chucker 83 grips the yarn bundle that has entered the suction air passage 78 by the operation of the cylinder 89 (ST).
6). Then, the package P is rotated by a predetermined angle, for example, 45 degrees by driving the rotation motor 34 (ST
7). After this rotation, the yarn chucker 83 releases the grip of the yarn bundle (ST8), newly sucks the yarn separated from the yarn bundle pressing member 77, and thereafter, until the rotation of the package P becomes one rotation. The operation is repeated to perform suction / traction over the entire circumference of the paper tube (ST 9). With this, bunch yarn 3 other than the required length
a and the yarn of the bunch rod winding 3b are removed from the end of the paper tube.

As described above, a predetermined position of the bunch feeding thread 3a is fixed by sticking a seal, and the bunch feeding thread 3a and the bunch rod winding 3b are cut by the heat cutter 70 in the vicinity thereof. , The suction air B in the substantially radial direction is acted on, and the cut bunch winding thread 3 is pulled in cooperation with the rotation of the package, so that the thread that has entered the slit can be easily pulled out. it can. That is, in the conventional bunch winding processing device, the bunch winding yarn 3 is drawn out long in the axial direction and then fixed and cut, and there is a possibility that the yarn may be broken in the middle. According to the present embodiment, yarn breakage at the portion beyond the seal is prevented, and the quality of the package P is improved.

Further, since a swirling flow is formed in the suction mouth 75 by the twisting nozzle portion 79 so as to twist the sucked yarn bundle, there is no single yarn breakage, and the yarn cut into the slit can be reliably formed. Can be removed. A thread bundle holding member 77 is provided near the suction mouth 75 so that the cut thread is sucked little by little. Thus, the thread at a position away from the suction port 76 of the suction mouth 75 is sucked. It is possible to cleanly remove the portion of the single yarn that does not clump, and to prevent the yarn in the slit from remaining in a fluffy shape.

Next, another specific embodiment of the present invention will be described with reference to FIG.

In this specific embodiment, an injection needle-shaped thin tube that is appropriately bent is used as the feed claw member 101 of the thread pulling mechanism, and the tip 102 is bent so as to follow the surface of the paper tube 9. (See FIG. 14). An air hose 103 for supplying compressed air is attached to the base end of the feed claw member 101.
By blowing air from the tip 102, the tip 102 is configured not to get on the bunch yarn feeder 3a when coming into contact with the surface of the paper tube 9.

The feed claw member 101 is connected to the moving block 45.
Are supported swingably via a leaf spring 104 and an elastic tube 114. The leaf spring 104 urges the feed claw member 101 downward. Then, in order to raise the feed claw member 101 from the surface of the paper tube, an air cylinder substantially upright
105 are provided. In this air cylinder 105, the forward / backward rod 106 is directed downward, and the distal end of the forward / backward rod 106 is bolted to the base end of a leaf spring 107 by a U-shaped rod 107.
It is fixed at. And the main body cylindrical portion 109 is a leaf spring 104
Is connected by another U-shaped rod 110 to the front end of the rod. That is, by controlling the supply of compressed air to the air cylinder 105, the main body cylindrical portion 109 rises due to the extension of the reciprocating rod 106, and the plate spring 104
Is lifted to move the feed claw member 101 upward.

Further, a sheet 112 on which a strip-shaped mark 111 extending in the longitudinal direction is drawn is attached on the upper surface of the feed claw member 101, and an optical sensor 113 for sensing the mark 111 is attached.
Is provided above it. This optical sensor 113
It is held by a leaf spring 104 via a bracket (not shown). Therefore, when the feed claw member 101 swings by a predetermined amount or more, the optical sensor 113 detects that there is no mark, so that it is determined that the number of windings is insufficient, and an alarm is issued.

With this configuration, the bunch yarn feeder 3a is connected to the feed claw member.
As a result, the winding can be more reliably aligned and the number of turns can be detected with a relatively simple structure. The other configurations, functions and effects are the same as those of the above-described specific embodiment.
